[css] 使用 Columns 調整電腦與手機的網頁畫面

flex 和 grid 讓我們能夠很簡單的去設定 RWD,讓網頁在電腦或手機畫面上都不會跑版,以 flex 來舉例,只需要使用 Media Query 在 width 等於手機 width 的時候,去調整 flex-direction 就好。

但除了這兩個語法外,我們也可以利用 columns 來調整畫面。

假設今天我們需要將文字分成兩列(column),可以直接用 columns 語法達到這個效果。

調整前:

index.html
<div class="content">  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.</p>  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.</p>  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.</p>  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.</p></div>

Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

調整後:

index.html
<style>  .content {    columns: 2;  }</style><div class="content">  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.</p>  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.</p>  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.</p>  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.</p></div>

Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

區塊

我們也可以把文字換成區塊,columns 語法一樣能正常運行。

index.html
<style>  .content {    columns: 2;  }  .content .box:nth-child(odd) {    background-color: #dd5353;  }  .content .box:nth-child(even) {    background-color: #ff731d;  }</style><div class="content">  <div class="box">    Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.  </div>  <div class="box">    Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.  </div>  <div class="box">    Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.  </div>  <div class="box">    Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.  </div></div>
Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.
Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.
Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.
Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.

Media Query

但是當畫面縮小的時候會發現區塊內的文字被擠成一團了,畫面上的文字也不好閱讀。

這時我們可以使用 Media Query 來調整,當畫面縮小到一定大小時,直接將 column 改成 1,意思就是每一列只會顯示一個區塊。

index.html
<style>  .content {    columns: 2;  }  .content .box:nth-child(odd) {    background-color: #dd5353;  }  .content .box:nth-child(even) {    background-color: #ff731d;  }  @media (max-width: 40rem) {    .content {      columns: 1;    }  }</style><div class="content">  <div class="box">    Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.  </div>  <div class="box">    Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.  </div>  <div class="box">    Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.  </div>  <div class="box">    Lorem ipsum dolor sit amet consectetur adipisicing elit. Quae, atque.  </div></div>

大家也可以用 CodeSandbox 來玩看看,將畫面縮小拉大,或是將 Media Query 註解掉,再縮小拉大,看會發生什麼事情。
